Brand: Globe Scientific

Antistatic Polystyrene Weighing Boats, 7–350 mL, 14 Sizes, 500/Case

Globe Scientific Weighing Boats are molded from clear, rigid polystyrene with an antistatic surface that prevents powders and granular samples from clinging during transfer. Bench scientists rely on these dishes for weighing reagents on analytical balances, prepping media components, and dispensing samples into reaction vessels without residue loss.

Frequently Asked Questions

Are these weighing boats antistatic?

Yes. The polystyrene surface is treated to reduce static buildup, which keeps fine powders from creeping up the walls and ensures accurate transfer onto a balance pan.

Can I use these boats with organic solvents?

They handle aqueous buffers, dilute acids, and dilute bases well. Aromatic and chlorinated solvents attack polystyrene and should be avoided; limit alcohol contact to brief exposures.
